The list of available switch styles goes on and on (and off?). Naturally, as mechanical complexity goes up, so (generally) does price. Hence simpler generally translates to cheaper. Figure 1 goes for ...

The venerable Stephen Woodward recently published the design idea (DI) “Flip ON flop OFF” that converts a momentary push button to a classic push-on, push-off switch. Figure 1 is an attempt to go ...

You can build a touch switch quite easily with old-school chips ... This operation is easy to achieve with a simple flip-flop constructed with old-school logic to create a “bistable” circuit.
